The erect or pendulous inflorescence is a loose many-flowered terminal panicle, 20–30 cm (8–12 in) long.

The individual flowers are 10–15 mm (0.4–0.6 in) long and have the general shape of members of the subfamily Faboideae.

In K. tenasserimensis, the inner surface of the standard is dark purple to maroon with a pale yellow nectar guide.

The genus name refers to Kanburi, the old name for the province of Kanchanaburi in western Thailand where the type species, K. chlorantha, was discovered.

[2] Kanburia is placed in the tribe Wisterieae, where it forms a clade with the genera Afgekia, Callerya, Serawaia and Whitfordiodendron.
